Metallic corrosion can be delayed using corrosion inhibitors. However, several industrial corrosion inhibitors are toxic and harmful to the environment and to the human health. In this context, in the last decades, research has been developed to investigate the performance of low toxicity corrosion inhibitors as green inhibitors obtained from vegetables, which are environmentally acceptable. The present work studied the corrosion inhibition efficiency of peel garlic extract (Allium sativum. L.) for possible replacement of benzotriazole (BTAH) on the corrosion inhibition of ASTM 1020 carbon steel (CS-1020) in 0.5 mol.L -1 hydrochloric acid media. Weight loss measurements, anodic and cathodic potentiodynamic curves and electrochemical impedance (EIS) experiments were carried out. The Fourier transformed infrared spectroscopy (FTIR) was carried out to evaluate the chemical compounds. The morphological characterization was obtained to observe the inhibitor effect in the corrosion products on substrate surface. The results showed that the addition of both inhibitors effectively hinder the corrosion process and indicated their adsorption on the electrode surface. The inhibiting efficiency of the peel garlic extract was only slightly inferior to BTAH showing that the former inhibitor can be an environmentally friendly option to toxic inhibitors. The FTIR analysis showed the presence of chemical compounds which presents antioxidant properties.

“…As observed, the η ML % were unchanged; this suggests that the inhibition mechanism of the extract was independent on the storage time, so it could be preserved without specific condition of time and temperature. This result was confirmed in the literature for some natural inhibitors (Abdel-Gaber et al , 2008; Zaabar et al , 2014).…”

Purpose This paper aims to evaluate the inhibitive potential of borage flowers’ aqueous extract (BFAE), Borago officinalis L., against the corrosion of mild steel in 1.0 M phosphoric acid. Design/methodology/approach Evaluation was carried out by chemical hydrogen evolution (HE), mass loss (ML) and electrochemical potentiodynamic polarization (PDP) measurements. SEM-EDX analysis also was used to confirm the existence of the adsorbed film. Findings It was found that the inhibition efficiency of BFAE increases with the increase in its concentration, but decreases with the increase in temperature. The potentiodynamic polarization curves indicated that BFAE acts as a mixed-type inhibitor with a predominantly anodic action. The adsorption of BFAE on mild steel surface was found to obey Langmuir and thermodynamic-kinetic adsorption isotherms by forming a thin film on the metal surface. SEM-EDX analysis confirms the corrosion inhibition ability of BFEA in 1.0 M H3PO4 by forming a thin film on mild steel surface. In this study, the inhibitive action of BFAE components is discussed on the basis of the physical adsorption mechanism. The same results were obtained for both the freshly prepared extract and the one that kept in a refrigerator for one year. Originality/value This paper indicates that BFAE can act as a good inhibitor for the corrosion of mild steel in 1.0 M H3PO4 even after one year of preparation.

“…Strict environmental laws and environmental awareness in the scientific world have directed researchers to develop other forms of so-called "green" inhibitors. Recently, various parts of plants, leaves, fruits, seeds and flowers were extracted and used as corrosion inhibitors [36][37][38][39][40][41][42][43][44][45][46]. Therefore, in recent years there has been a particular interest in the activity of essential oils as a corrosion inhibitor of steel in hydrochloric acid [47][48][49][50][51][52].…”

Natural and aromatic substances contained in plants which can be extracted by hydro-distillation or by cold extraction, more commonly known as essential oils are used today in several fields including cosmetic, perfumery, food processing, traditional medicine, agriculture etc. More recently, a strong use of these products extracted from plants as a corrosion inhibitor of metals and alloys in an acidic environment has been observed, given the number of works that have been published in recent decades. This review represents a general study on essential oils for a better understanding of these natural products, but also a non-exhaustive study of the published research works on the use of essential oils as a corrosion inhibitor of metals and alloys, in particular mild steels in acidic environments. Most of these studies have revealed great potentials of essential oils in inhibiting the corrosion of metals in aggressive environment, such as acidic environment. Thus, they have proposed alternatives to artificial metal corrosion inhibitor known to cause environmental pollution and public health issues. This review is a contribution to research efforts carried out by scientific community to find green corrosion inhibitors. It lays the basis for future research work aimed to investigate on the corrosion inhibition properties of essential oils extracted from Senegalese local plants.
